我正在尝试为我的应用程序创建一个身份验证系统。当我编译代码时，Android Studio 会抛出以下错误

java.lang.NoSuchMethodError: No virtual method setDeviceCredentialAllowed(Z)Landroid/hardware/biometrics/BiometricPrompt$Builder; in class Landroid/hardware/biometrics/BiometricPrompt$Builder; or its super classes (declaration of 'android.hardware.biometrics.BiometricPrompt$Builder' appears in /system/framework/framework.jar)

我遵循了一些其他可能的解决方案，例如Invalidating Caches and Restarting my Android Studio但它没有解决问题

我在用 androidx.biometric:biometric:1.0.0-alpha03

    KeyguardManager keyguardManager = (KeyguardManager) getApplication().getSystemService(KEYGUARD_SERVICE);
            if(keyguardManager.isKeyguardSecure()){
                Toast.makeText(this,"Using keyguard",Toast.LENGTH_SHORT).show();
                Builder biometricPromptBuilder = new Builder(this);

                biometricPromptBuilder.setTitle("Title");
                biometricPromptBuilder.setSubtitle("Subtitle");
                biometricPromptBuilder.setDescription("Discription");
                biometricPromptBuilder.setNegativeButton("Cancel", newExecutor, new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialogInterface, int i) {

                    }
                });
                biometricPromptBuilder.setDeviceCredentialAllowed(true);
                android.hardware.biometrics.BiometricPrompt biometricPrompt = biometricPromptBuilder.build();
                CancellationSignal cancellationSignal = new CancellationSignal();
                biometricPrompt.authenticate(cancellationSignal, newExecutor, new android.hardware.biometrics.BiometricPrompt.AuthenticationCallback() {
                    @Override
                    public void onAuthenticationError(int errorCode, CharSequence errString) {
                        super.onAuthenticationError(errorCode, errString);
                    }

                    @Override
                    public void onAuthenticationHelp(int helpCode, CharSequence helpString) {
                        super.onAuthenticationHelp(helpCode, helpString);
                    }

                    @Override
                    public void onAuthenticationSucceeded(android.hardware.biometrics.BiometricPrompt.AuthenticationResult result) {
                        super.onAuthenticationSucceeded(result);
                    }

                    @Override
                    public void onAuthenticationFailed() {
                        super.onAuthenticationFailed();
                    }
                });
            }
        }

预期的输出应该是 App 的成功编译

androidxAPI发布于，而beta01框架(android.hardware.biometrics)API 发布于29.

编辑：只需重新阅读您的帖子，您正在使用框架的 API 版本。您的目标 API 级别是多少？该框架的版本仅可用29+。您应该考虑使用androidx.biometricAPI 的版本。
